C# and Objects/Classes
- by user1192890
I have tried to compile code from Deitel's C# 2010 for programmers. I copied it exactly out of the book, but it still can't find main, even though I declared it in one of the classes. Here is a look at the two classes:
For GradeBookTest:
// Fig. 4.2: GradeBookTest.cs
// Create a GradeBook object and call its DisplayMessage method.
public class GradeBookTest
{
// Main method begins program execution
public static void Main(string[] args)
{
// create a GradeBook object and assign it to myGradeBook
GradeBook myGradeBook = new GradeBook();
// call myGradeBook's DisplayMessage method
myGradeBook.DisplayMessage();
} // end Main
} // end class GradeBookTest
Now for the GradeBook class:
// Fig. 4.1: GradeBook.cs
// Class declaration with one method.
using System;
public class GradeBook
{
// display a welcome message to the GradeBook user
public void DisplayMessage()
{
Console.WriteLine( "Welcome to the Grade Book!" );
} // end method DisplayMessage
} // end class GradeBook
That is how I copied them. Here is how they appeared in the book:
1 // Fig. 4.2: GradeBookTest.cs
2 // Create a GradeBook object and call its DisplayMessage method.
3 public class GradeBookTest
4 {
5 // Main method begins program execution
6 public static void Main( string[] args )
7 {
8 // create a GradeBook object and assign it to myGradeBook
9 GradeBook myGradeBook = new GradeBook();
10
11 // call myGradeBook's DisplayMessage method
12 myGradeBook.DisplayMessage();
13 } // end Main
14 } // end class GradeBookTest
and
// Fig. 4.1: GradeBook.cs
// Class declaration with one method.
using System;
public class GradeBook
{
// display a welcome message to the GradeBook user
public void DisplayMessage()
{
Console.WriteLine( "Welcome to the Grade Book!" );
} // end method DisplayMessage
} // end class GradeBook
I don't see why they are not working. Right now I am using Visual Studio Pro 2010. Any Thoughts?
